To boost his flagging campaign, should John McCain pledge to serve just one term if elected?

Pundits have suggested that Sen. McCain could win over undecided voters if he promises to serve just one term. Such a strategy would enable him to be bolder in his policies, because he would not have to answer to voters or his party if he did not seek re-election.

Would this work? Or would it appear to be a ploy? What else might Sen. McCain do to persuade voters who are on the fence?
